MX Hunting Co. Named Official Outfitter for Desert Bighorn Sheep Hunts on Isla Tiburón — 2026/27 Season
Sonora, Mexico — MX Hunting Co. is proud to announce our formal partnership with the Comcáac (Seri) people, the traditional owners and stewards of Isla Tiburón. For the 2026/27 season, we are the official outfitter for desert bighorn sheep hunting on the island.
“This has been a long time coming,” said Justin Richins and Jesus “Chuy” Murillo of MX Hunting Co. “We’ve spent years building real trust with the Comcáac family, and we’re honored they chose us to handle their bighorn hunts. They own and steward the island. We take care of the guiding, boats, camps, and logistics so hunters get there safe and have a good experience. It’s a true partnership — they open the access, and we make the hunts happen.”
Working Side by Side Every hunt puts our guides shoulder-to-shoulder with Comcáac guides and packers. These guys know every ridge and canyon on Tiburón — they grew up with it. That local knowledge is something no outside outfit can touch.
We’re excited to get serious, ethical hunters onto this remote bighorn hunt. It’s one of the most tightly controlled in North America.
Long-Term Commitment We’re not here for one season and gone. We’re in it for the long run. Every tag fee goes straight to the Comcáac tribe, and they benefit by putting their own people to work as guides, packers, and boat captains. That money supports the families who protect the island day in and day out.
We want Tiburón to be known for solid rams and good, responsible management by the tribe.
Poaching Enforcement Poaching is not allowed on the island. 2026/27 There’s a new & strong system in place with three groups working together: SEMARNAT (federal wildlife authority) Sonora State Wildlife Enforcement. The Comcáac (Seri) Tribal Authority
They take it seriously and it gets enforced.
Sheldoni Mule Deer Update After their recent population assessment, the Comcáac decided to hold off on Sheldoni mule deer tags for 2026-2027. They’re focusing on genetics, age structure, and letting the herd build back up. In addition to the biological reasons, closing the island to deer will also help with access and preventing poaching. We back their call 100% — it’s the smart move when the numbers say the herd needs a break.
About Isla Tiburón Mexico’s largest island lies in the Gulf of California off the Sonoran coast. Access is strictly controlled, and hunting only happens through the limited tag system run by the state and the Comcáac. It’s a biosphere reserve with desert bighorn sheep and the unique Sheldoni mule deer.
About the Comcáac (Seri) People The Comcáac have been the stewards of the Sonoran coast and Isla Tiburón for thousands of years. All permits go through them, and their people are on the ground for every hunt.
